Abstract (en)
[origin: WO9803332A1] The present invention relates to a laminated packaging material suitable for use especially in heat-sealable packages for liquid food, such as milk, cream and juice cartons, and to a manufacturing method of the material, and to a food package manufactured of the material. The material comprises a core of paper or cardboard, and oxygen and aroma proof barrier layers of EVOH and polyamide; it is characteristic of the invention that the EVOH layer (5) and the polyamide layer (4) are joined together directly without any intermediate adhesive layer, and that the barrier layers and the core (3) are interposed between polymeric heat-sealing layers (2, 7) on both sides of the material. The material is manufactured by extrusion so that at least the materials of the said barrier layers (4, 5) are placed against each other in a molten state and forwarded to the core (3) in one web.
